TL;DR: The use of 2-naphthylamine as promoter in the enantioselective Friedlaender condensation of o-aminobenzaldehydes with p-substituted cyclohexanones provides access to tetrahydroacridine derivatives in high yields and excellent enanti-lectivity as mentioned in this paper.
Abstract: Use of 2-naphthylamine as promoter in the enantioselective Friedlaender condensation of o-aminobenzaldehydes with p-substituted cyclohexanones provides access to tetrahydroacridine derivatives in high yields and excellent enantioselectivity (up to 95%).
